Write a system of equations for the following applications and then solve using matrices in a calculator. Must include:
3 equations
MATRIX (if you want to use the "table" feature use a 4x3 table OR you can upload a screenshot from Desmos or a picture of your paper
and
solution WITH UNITS in your answer
I have a jar of nickels, dimes and quarters that totals $6.95. There are 63 coins altogether in the jar. There are half as many dimes as nickels. Find the number of nickels, dimes and quarters in the collection.

Solution:

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
